Lacticaseibacillus paracasei strain S49

Lacticaseibacillus paracasei strain S49 is a Gram-positive, non-motile rod-shaped bacterium that exhibits a facultative anaerobic metabolism. This strain is characterized by its arrangement in chains and is categorized as mesophilic, with an optimal growth temperature of 30°C. It possesses a single membrane and contains one replicon. This bacterium has a free-living biotic relationship and has been identified in multiple habitats, including those associated with various hosts such as Homo sapiens (humans), Oryctolagus cuniculus (domestic rabbits), and Panax ginseng (a medicinal plant). Notably, Lacticaseibacillus paracasei strain S49 has been studied for its health effects, particularly in relation to graft-versus-host disease (GvHD), indicating potential implications for human health and therapeutic applications. The presence of flagella suggests a degree of adaptability in its environment, although it is not mobile. The ability to thrive in different habitats and its interactions with various hosts may provide insights into its ecological role and potential benefits in microbiota management or probiotic applications. Understanding the traits of Lacticaseibacillus paracasei strain S49 can inform research into its functions and applications in health and disease management.
